Сreation of a long-term tree-ring calendar chronology based on archaeological wood in the Novosibirsk region is directly linked with mass dating of wooden buildings. In 2021, for the first time, successful calendar dating of two wooden houses located in Sarachevka, the Novosibirsk Region, was carried out. To study the architectural appearance of each building, a 3D model was built using a high-resolution camera installed aboard an unmannedflying machine. The dendrochronological method was used to date buildings. Cameralprocessing of the samples was carried out according to the standard procedure. Dating of the houses was carried out in two stages: for both of them, a “floating” chronology it was created, after which each of them were standardized and dated relative to the 377-year regional tree-ring chronology. As a result of this, 14 samples from building No. 1 were dated. It was found out that the wood for construction of the building was harvested not earlier than 1904, although the building itself was erected at the beginning of the 20th century. From building No. 2, 10 samples were dated, which made it possible to assert that the wood for the construction was harvested not earlier than 1907, although the building itself was erected in the first quarter of the 20th century. The obtained results updated the dates based the architectural features of both buildings by more than half a century and proved that the archaic features of traditional house building, which were brought by the Russian population to the Novosibirsk Region, preserved until the beginning of the 20th century.
